You have saved up for months to buy a new bike. As you're getting ready to buy it, a child runs by and steals your money. You chase him down and find that his mother is deathly ill and the child stole the money to buy her medicine.
That's their problem, I didn't get the lady sick. I worked hard for that money and it's mine.
Perhaps you would have helped them if they were to ask, but you don't help thieves.
Maybe I'll let them keep some of the money and buy the bike later.
They are obviously in need of the money more than I. I give it all to them.
I'll give them the money and try and nurse the mother back to health.
Refuse to give them your money, but still try and nurse the mother back to health.
